Description

Technical Field

[0001] The present invention relates to the technical field of robots, and in particular to an inspection robot chassis with a detachable buffer structure. Background Art

[0002] A robot is a machine device that can perform work automatically. It executes actions through human command, pre-programming or intelligently specified principles. Its main function is to assist or replace humans in completing corresponding tasks. When the robot encounters an obstacle while moving forward or backward, the robot collides with the obstacle. The impact force generated by the chassis after the collision can easily make it difficult for the robot to maintain balance, resulting in collapse and damage.

[0003] Therefore, it is necessary to propose a patrol robot chassis with a detachable buffer structure, which can solve the problem that the impact force generated when the robot collides with an obstacle can easily cause the robot to collapse and be damaged. Summary of the Invention

[0004] The purpose of the present invention is to provide an inspection robot chassis with a detachable buffer structure to address the problem that the robot may easily fall and be damaged due to the impact force generated when colliding with an obstacle during movement.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] A patrol robot chassis with a detachable buffer structure comprises a chassis frame, a walking mechanism is provided on the chassis frame, and buffer devices are provided at the front and rear ends of the chassis frame, and the buffer devices are used to suppress the impact of the robot's movement and collision.

[0007] The robot is set on the chassis frame and is driven to move by the walking mechanism. Buffer devices are provided at the front and rear ends of the chassis frame. When the mobile robot collides with the outside world during walking, the buffer device acts as a buffer to suppress the impact of the collision. This device has a simple structure and solves the problem that the robot collides with obstacles during movement, and the impact force generated can easily cause the robot to fall over and be damaged.

[0008] Preferably, the buffer device includes a first clamping plate, a second clamping plate, and a buffer shaft, with both ends of the buffer shaft connected to the first and second clamping plates, respectively. A plurality of springs are further disposed between the first and second clamping plates, with all of the springs disposed between the buffer shafts. When the first clamping plate collides head-on with an obstacle, the buffer shaft and springs act as a buffer, suppressing the impact of the collision and preventing the robot from tipping over, providing excellent impact protection.

[0009] Preferably, the first clamping plate has a through hole, one end of the buffer shaft is slidably connected to the through hole, and the other end of the buffer shaft is fixedly connected to the second clamping plate; both ends of the springs are detachably connected to the first and second clamping plates. When the portion of the first clamping plate near the buffer shaft collides with an obstacle, the buffer shaft moves within the through hole to abut the obstacle, and the buffer shaft contracts, thereby suppressing the impact of the collision, and providing a good buffering effect for the impact of a portion of the first clamping plate on the obstacle.

[0010] Preferably, the buffer shaft is clearance-fitted with the through hole.

[0011] Preferably, the buffer device is detachably connected to the chassis frame.

[0012] Preferably, the walking mechanism includes a motor and a power supply, the output end of the motor is fixedly connected to a first rotating shaft, the first rotating shaft is fixedly connected to a driving gear, the driving gear is engaged with a driven gear, the driven gear is engaged with a second rotating shaft, and the second rotating shaft is fixedly connected to the wheel.

[0013] Preferably, a warning light is further provided on the chassis frame, and the power supply is electrically connected to the warning light.

[0014] Preferably, a buzzer is further provided on the chassis frame, and the power supply is electrically connected to the buzzer.

[0015] Compared with the prior art, the advantages of the present invention are: the present invention is a patrol robot chassis with a detachable buffer structure, and the front and rear ends of the chassis frame are provided with buffer devices. When the mobile robot collides with the outside world during walking, it plays a buffering role and suppresses the impact of the collision. The structure of this device is simple, and it solves the problem that the robot collides with obstacles during movement, and the impact force generated can easily cause the robot to fall and be damaged.

[0016] The beneficial effects of other embodiments of the present application are:

[0017] 1. When the first splint collides with an obstacle head-on, the buffer shaft and spring can suppress the impact of the collision, thereby preventing the robot from tipping over and having a good anti-impact effect.

[0018] 2. When the portion of the first splint close to the buffer shaft collides with an obstacle, the buffer shaft moves in the through hole and abuts against the obstacle, and the buffer shaft contracts, which can suppress the impact of the collision and has a good buffering effect on the collision of a part of the first splint with the obstacle.
